Research Progress of Radiofrequency Ablation in the Treatment of Spinal Metastases

脊柱转移瘤在癌症晚期患者中很常见，可导致疼痛、神经功能缺损、生活质量下降和接受癌症系统治疗的能力降低。由于脊柱转移瘤患者预期生存期较短，治疗原则多以姑息性治疗为主。在临床上，积极的手术干预在局部肿瘤控制方面提供了更好的疗效。但传统手术存在开放创面大、操作出血多、术后康复长等临床问题，使得术后并发症发生率较高。随着治疗理念的不断进步，射频消融术开始应用于治疗脊柱转移瘤并取得了优异疗效。本文就射频消融术的工作原理、影像学引导、应用现状进行如下综述。Spinal metastases are common in patients with advanced cancer, which can cause pain, neurological deficits, decreased quality of life and reduced ability to receive systemic cancer treatment. Due to the short expected survival of patients with spinal metastases, the treatment principle is mostly palliative. In clinical practice, active surgical intervention provides better local tumor control. However, traditional surgery has clinical problems such as large open wounds, excessive intraoperative bleeding and long postoperative recovery, resulting in a high incidence of postoperative complications. With the continuous progress of treatment concepts, radiofrequency ablation has been applied to the treatment of spinal metastases and has achieved excellent results. This article reviews the working principle, imaging guidance and application status of radiofrequency ablation.
